I have a 1.5HP Pentair Whisper Flo 2 speed pump (WFDS-6 product # 011522) that seems to be leaking under the unit. On high speed water level in the filter basket is good, but once it's on low speed the water lever decreases. Water level in the filter tank drops as well whenever it runs on low speed.
Went out this morning after the pump had been on for about 5 hours & there was only an inch or two water in the bottom of the basket, filter tank was empty & no water was being pumped whatsoever. shut off pump immediately. Ran it again this afternoon on high & low for 10 minutes. Though it seemed be moving water adequately, the pump was extremely hot to the touch. The pump is about 4 years old at this point.
Not sure what to do next. My pool equipment expertise is minimal, but i'm handy enough if i had an idea of what needs to be fixed.
Thanks for the help.
